| Zusammenfassung: | The invention discloses a method for machining ultrathin wall sleeve parts. The method includes the first step of carrying out normalizing treatment on a forge piece, the second step of carrying out rough-turning, the third step of carrying out the first ageing and distressing treatment, the fourth step of carrying out semi-finish-turning, the fifth step of carrying out the second ageing and distressing treatment, the sixth step of carrying out finish-turning on an inner hole and semi-finish-turning outer circles, the seventh step of carrying out the third ageing and distressing treatment, the eighth step of carrying out finish-turning on the small end, the ninth step of carrying out finish-turning on the outer circles, and the tenth step of carrying out ultra-finish-turning on the outer circles. The cylindricity of the outer circles of a finished ultrathin wall sleeve through the method is smaller than or equal to 0.02, and the wall thickness difference of the finished ultrathin wall sleeve is smaller than o |
